The length of inside groove 3 is internal thread 1 and twists to the twices of the back width of thread of coincideing with external screw thread 4, and the nib length of normally exposing out slightly is less than the half the of 3 length of inside groove, and the weight of the pen socket is suitable, and when a landing or when aloft rolling, pen socket landing in time is with the nib free accommodation to reach the effect of better protection nib.

Description

An a kind of shell

Technical field

The utility model relates to an a kind of shell technology field.

Background technology

In the face of numerous things needing memory, as word, numeral, human history record etc., and the memory of people is limited, the thing followed creates a series of " pen ", as writing brush, water-color paintbrush, ball pen, pencil etc., in the face of different situations needs different pens, therefore the importance of appearance to the mankind of " pen " is self-evident.But along with people are to the use of water-color paintbrush, ball pen, it is found that a problem, when this two classes pen drops on the ground from certain altitude, and when nib has a situation about landing, this pen core all can not re-use substantially, thus creates wasting phenomenon.The utility model proposes to solve this kind of phenomenon preferably.

Summary of the invention

The utility model technical issues that need to address are: " pen " is that the mankind commonly use the important tool recording things, in daily life, its use is ubiquitous, but people use also to have in it tumbled on the ground because of carelessness time, if at this moment nib first lands, pen core probably can not reuse, and the utility model first lands to solve nib exactly, and pen core still can use this problem.

Technical solution of the present utility model is: an a kind of shell, in composition structure, comprises internal thread 1, slide plate 2, inside groove 3, external screw thread 4, joint face 5, passage 6.The pen cap is made up of internal thread 1, slide plate 2, and the weight of the pen cap should suitably lay particular stress on, so that can landing in time be encased by nib when a landing or rolling aloft, internal thread 1 in the pen cap should the right side of the external screw thread 4 of penholder in fig. 2, and internal thread 1 and external screw thread 4 just supporting, the outside of a whole shell should be designed more coarse, to increase the frictional force between shell and hand, when slide plate 2 is when the rightmost side of inside groove 3, the nib of pen core can expose over half, now the distance of the bottom screw thread of internal thread 1 and an external screw thread 4 rightmost screw thread is the half of interior slot length, when slide plate 2 is at inside groove 3 middle, nib can encase by the pen cap completely, and pen cap foot and nib have suitable distance, the now bottom screw thread of internal thread 1 and external screw thread 4 rightmost thread contact, after internal thread 1 and external screw thread 4 are screwed to the place that fits like a glove, slide plate 2 leftmost side contacts, slide plate 2 is only limitted to slidably reciprocate in inside groove 3.Design internal thread 1 and the object of external screw thread 4 are in order to when not use, are played a protective role by rotating female screw 1 and external screw thread 4 pairs of nibs.As being screwed to connect face 5 to replacing pen core, penholder is divided into two parts, joint face 5 is made up of internal and external threads.Passage 6 designs to keep the pressure of penholder inside and outside.The outside design of whole pen has the effect of friction when people should be allowed to use.The utility model has compared with traditional pen: when pen lands, protect pen core preferably, the advantage cut the waste.

In figure: 1-internal thread, 2-slide plate, 3-inside groove, 4-external screw thread, 5-joint face, 6-passage.

Detailed description of the invention

Below in conjunction with Figure of description, the utility model is described in further detail.

As shown in Figure 1, the pen cap is made up of internal thread 1 and slide plate 2; As shown in Figure 2, penholder is made up of inside groove 3, external screw thread 4, joint face 5 and passage 6; An a kind of shell is made up of the pen cap and penholder.

Internal thread 1 and external screw thread 4 supporting, slide plate 2 can only slidably reciprocate in inside groove 3, the length of inside groove 3 is the twice that internal thread 1 and external screw thread 4 are screwed to identical rear thread width, namely when slide plate 2 slides into the rightmost side of inside groove 3, the distance of the nethermost screw thread of internal thread 1 and the screw thread of external screw thread 4 rightmost side equals the width of internal thread 1 or external screw thread 4, or equal the half of inside groove 3 length, now expose most of nib, person easy to use is used for writing.When internal thread 1 just contacts with external screw thread 4, nib encases by the pen cap just completely, thus plays the effect of protection nib.

Due to when this kind of pen of use, user needs the pen cap up to slide certain distance, thus nib is exposed for writing, so need to clamp the pen cap with finger in the process of writing, in order to allow finger easier clamp the pen cap, the friction effect that the outside design of whole pen should allow it contact with hand is more better.

Claims (2)

1. one kind of shell, it is characterized in that: in composition structure, comprise internal thread (1), slide plate (2), inside groove (3), external screw thread (4), joint face (5), passage (6), the pen cap is made up of internal thread (1), slide plate (2), internal thread (1) in the pen cap should on the right side of the external screw thread of penholder (4), and internal thread (1) and external screw thread (4) just supporting, the outside of a whole shell should be designed more coarse.

2. an one according to claim 1 shell, it is characterized in that: when slide plate (2) is when the rightmost side of inside groove (3), the nib of pen core can expose over half, now the distance of the bottom screw thread of internal thread (1) and external screw thread (4) rightmost screw thread is the half of interior slot length, when slide plate (2) is at inside groove (3) middle, nib can encase by the pen cap completely, the now bottom screw thread of internal thread (1) and external screw thread (4) rightmost thread contact, after internal thread (1) and external screw thread (4) are screwed to the place that fits like a glove, slide plate (2) leftmost side contacts, slide plate (2) is only limitted to slidably reciprocate in inside groove (3).
